During a normal day, we are constantly authenticating our user credentials to web sites, file servers, and other network resources. As with most technologies, there’s more than one way to perform these authentications. In this video, you’ll learn what’s happening over the wire and become familiar with PKI, Kerberos, AAA, network access control technologies, CHAP, EAP, and much more.
The network is a wide-open space, but there are a number of technologies that network and security professionals can use to help control access to critical parts of the network. In this modules, you’ll learn about filtering technologies, tunneling and encryption methods, and remote access applications and protocols.
Firewalls are one of the most fundamental security components in our modern networks, but not all firewalls are created equally. In this module, you’ll learn about common features of modern firewalls, such as network-layer and application-layer firewalls, stateful vs. stateless operation, content filtering, signature identification, and zone-based security.
Have you ever seen the wiring closet of a relatively large network? It’s a mix of cables, punch-down blocks, and patch panels. In this video, you’ll learn about those wiring distribution technologies and how to verify the wiring installation and termination of your network infrastructure.
Once a network is in place, there are many different ways to communicate to other devices. In this video, you’ll learn about peer to peer, client/server, VPNs, and VLANs.
Ethernet is the King of the LAN, and in this video we’ll go into details about 10 megabit, 100 megabit, 1 gigabit, and 10 gigabit Ethernet versions. If it runs Ethernet over copper or fiber, you’ll learn about it in this module!
Packet switched WAN networks are the latest technologies in wide area communication. In this video, you’ll learn about ATM, ADSL, MPLS, cable modem, and many more packet switched technologies.
In the first video of this two-part series on WAN technologies, we’ll examine the specifics of circuit switched WAN links. You’ll learn about POTS, T1s, and ISDN circuit switched technologies, and we’ll show you the speed differences, transmission media, and distance limitations.
Networking fundamentals include many different physical network topology types. In this video, we’ll detail the basic structure of star networks, mesh networks, ring networks, and much more.
